Application filed April 30, 1926. Serial No. 105,820.

Y This invention relates to a plow/share, one or the'ob]ects being toprovide a device of this character theV point and shearing por-` tionsof which can be made separate from the share so thatit is thus possibleto form efficient means whereby the separate parts Vao of the device canbe firmly attached to' each other, it being possible readily todisconnect a broken part and replace it withanew one without discardingthe entire plowshare.

1With the foregoingv and other objects in view which will appear as thedescription proceeds, the invention resides in the com'-V bination andarrangement of parts and in the details of construction hereinafterVdescribed and claimed, itbeing understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings,

Figure 1 is a top plan View ofa portion of a plowshare embodying thepresent improvements.' y

Figure 2 is a bottom plan view of the structure shown in Figure 1;

F'gure 3 is a section on line 8 8, Figure 2.

Figure 4 is a section on line 4 4, Figure 1.

Figure 5 is section on line 5 5, Figure 1.

Figure 6 is a top plan view of a portion of a modified form ofplowshare.

Figure 7 is a section on line 7 7, Figure 6.

Referring to the figures by characters of reference 1 designates theblade of the plowshare provided with a blunt nose 2 from the inner sideof which is extended a tongue 3 constituting an extension of a sideflange 4 formed beneath one side of the blade. This blade, with itsintegral tongue can be made of any suitable material such as cast iron,and, in the structure illustrated in Fig- Y ures 1 to 5 inclusive arecess 5 is provided in the upper .surface of the blade extending fromthe forward end or nose asV shown.

, Arranged in front of the nose of the blade 1 is a point 6 having anintegral shearing wing 7 extending obliquely therefrom at such an anglethat when the back end of the point is seated against the nose 2 thewing i will extend under the adjacent side portion of -thebladel asshown in Figure 4and will'project laterally beyond the blade lto providea shearing edge 8. The wing 7 can l adjacent edge portion of the' blade1 and a be vrecessed as illustrated at 9 to receive the desired numberof ears l() can be extended Y laterally from this recessed portion forthe reception ofbolts 11 the heads of which are countersunk into thebladc'l.` V Formed inthat side of the point remet from the wing 7 is a.longitudinal recess 12 for the-reception ofthe tongue 3, the end of thisrecess being preferably shaped to provide a recess or pocket 13 toreceive the l pointed end'14 of the tongue longitudinal groove 15 isformed in the top face of the point 6 and'is adapted to register withthe recess 5. The forward end portion of this groove widened as shown at16 so as to extend to one side of the point and this wide port-ion ofthe groove iside-eper than the remaining portion as shown at17, therebyproviding a transverse shoulder 18. n

The point 6 has a web 19 integral there- .with and extending under thenose or forward portion of blade 1. A wear plate 2O is fit-ted snugly inthe groove 15 and has athickened portion 21 seated within the deepl Thisthiclest portion 16 of the groove. ened portion provides a transverseshoulder 22 designed to bear against the shoulder 18.V

Plate 2O is of suicient length to extend into the recess 5 where it isfastened by a bolt 28 extending through the plate 20, nose 2 and web 19.As plate 2O isheld in the groovr 15 by rivets 24 or the like it will beap parent that the parts will thus `be held together securely. Plate 2Ocan be of avgoodV grade of steel audits forward end may, if desired,extend slightly beyond the front end of the point 6 so as to receivemost of the wear. Should this plate become worn yto .Sofi

an objectionable extent it could be removed from the point and anotherplate substituted. Should the point 6 or its wing 7 become broken orworn another one can be used in lieu thereof. Y

If desired, and as shown in Figures 6 and 7, the use of a separateconnecting plate 20 can be dispensed with. In this modified structurethe point 24 and its wing 25 have a web 26 integral therewith forextending underV the share 27. A recess 28 can be provided in the topsurface of the blade of the Y A share to receive atongue QQLintegral.with the point. Y Thus' Lvvhen a bolt BOis extendedlthrough the tongue,blade and web the parts i *Y will be held together securely as shown inFigure. Y Y a Y What 1s claimed 1s:
